mail/turba modifies /usr/local/www/horde/config/registry.php
and www/horde2 couldn't be completely deinstalled.
[Reported by SADA Kenji]
Fix: Remark: this PR bumps PORTREVISION for www/horde2 and mail/turba,
because I had forgotten to incr it in PR ports/38261 and 38263.
Pre-requisite: PR ports/38263 must be committed;
then apply these patches:
1) www/horde2 (only PORTREVISION)
How-To-Repeat: Install turba, deinstall it, then deinstall www/horde2.
